IMPROVEMENT |N SAFETY-PINS.

Specification formingipart of Letters Patent N01 199,511, dated January 22, 1878; application led December 24, 1877.

To all 'whom it may concerm k Be it known that I, WILLIAM A. BUTLER,

of the city, county, and State of New York,

have invented a new and useful Improvement in Safety-Pins, of which the following is a de;- scription, reference being had to the accompa-` nying drawing, forming part of this specifica.- tion. Y Y

This invention relates to shield or safety pins, or diaperpins,7 as they are commonly termed, in which a bent wire, formed preferably with a coil at the bend to give it increased elasticity, is attached at its one or unsharpened end with a shield, and made to engage with and disengage from the latter at its other or sharpened end.

The invention consists in a safety-pin of such description, made with or without a coil, of novel construction, whereby the unsharpened limb of the wire, which is attached to the shield, is bent or set off from the latter laterally,which not only gives a better nish to the pins, and indicates, especially when removing the pin in the dark, the engaging and disengaging end of the wire, but, while providing for an immovable attachment of the shield to the unsharpened limb of the wire, admits of the sharpened limb thereof being adjusted or worked around the shield from opposite sides or in reverse directions, to engage or disengage itself with or from the shield without risk of its catching or entanglement with the.

vguard-case, is protected by the latter, and prevented from catching in the cloth or article to which the pin is applied,

Figure l represents a longitudinal or side view of a safety-pin constructed in accordance with that part of my invention which relates to the formation of thelimb carrying the shield; Fig. 2, a longitudinal section of said pin, showing also a guard-case applied to the coil in the wire; Fig. 3, a transverse section on the line m w, and Fig. 4 a transverse section on the line y y. Fig. 5 is a view of a blank in illustration of one mode of constructing the guardcase. Fig.` 6 represents a longitudinal view, in part,'of the unsharpened limb of the wire,

vwith the shield attached thereto according to amodiiied construction of the pin; and Fig. 7, a sectional longitudinal view, in part,of another modiiication. Figs. 8, 9, l0, 11, and 12V are diagrams in illustration of various constructions ofthe shield of the pin.

Referring, in the -iirst instance, to Figs. 1, 2, and 3 of the drawing, A represents the unsharpened limb of the wire or pin, and B the pointed or sharpened limb thereof, said wire either being coiled' or not to give it elasticity where it is bent over to form said limbs, but

preferably formed with a coil, g, at such part.'

the shield to the unsharpened limb A, admit` ting of the sharpened limb B of the wire being adjusted or worked around the shield from opposite sides or in reverse directions to engage or disengage itself with or from the shield. This reversal of the sharpened limb of the pin relatively to the shield will be found very con venient both in engaging and disengaging said sharpened limb b with and from the shield (l, without any liability, by reason of the offset b, of the sharpened limb becoming entangled with or catching the unsharpened limb A.

The shield C, as shown in Figs. l and 3, may be formed by stamping and drawing it from sheet metal into a cup, and afterward making a slot, d, in its one side for the sharpened limb B of the wire to engage and disengage itself with and from the shield. The construction of the shield, however, admits of various modifications-thus: It may be made from either one of the several shaped blanks shown in Figs. 8,9, and 10, by suitably bending said blanks to form a slotted cup; or, instead of a slotted cup, it may be made with one of `its side edges overlapping the other,

leaving a space between .said edges for'tlie en-` try and removal of the sharpened limb of the pin, and may either be of circular or oval form in its transverse section, as shown in Figs. 11 and 12.

The unsharpened limb A of the wire Amay be attached to the shield C, to hold it from turning or working loose, by projecting the offset b thereof through the side or sides of the shield above its bottom, and uniting the same by solder e within said shield, as shown in Fig. 2.;V or the offset b may be projected through the base of the shield, as represented in Fig. 6, and be secured therein in any suitable manner; or, again, said offset may be projected through the one side of the shield, and the portion thereof entering the shield afterward be bent by a punch, as shown in Fig. 7 of the drawing.

When the wire of the pin is formed with a coil, g, to give the limbs increased elasticity, a guard-case, D, as shown in Figs. 2 and 4, may be combined with said coil to inclose or protect it in a free manner at its sides, and so prevent the coil from catching' in the cloth or article to which the pin is applied, or from becoming entangled with any exposed edge or portion of the cloth. This guard-case may be constructed from a blank shaped as in Fig. 5,

by bending s'aid blank at lits neck IL, to receive the coil at its sides within it, and afterward bending over the overlapping edges of the blank or projections thereon, to loosely close the guard-case onthe coil. Said guard-case, however, may be variously constructed, and be'made either with or Without a hole in the center-thus: It might be made of independent side pieces or caps, united either by a solid or hollow rivet through the center of the coil; or it might be otherwise constructed to protect or inclose the coil without restricting the working of the latter when closing and opening the pin.

I claiml. A safety-pin having the unsharpened limb of the wire rigidly attached to the guard or shield, and bent or extended laterally from the side of the said guard orl shield, whereby the latter is supported oii' from the limb which carries it, substantially as described.` A

2. The guard-case D, in combination with the coil g of the Wire of the pin, essentially as described.
